implement your local notification code:

var androidPlatformChannel = new AndroidNotificationDetails(
    "your_channel_id", "name", "desc_channel",
    sound: RawResourceAndroidNotificationSound('lawgo_sound_notification'),
    playSound: true,
    importance: Importance.Max,
    priority: Priority.High);

add onResume, OnLaunch support, when apps run on background notification payload should be setup to this:

{ "notification" : {
     "body" : "Body of Your Notification",
     "title": "Title of Your Notification",
     "android_channel_id": "your_channel_id"
 },
 "data" : {
     "body" : "Body of Your Notification in Data",
     "title": "Title of Your Notification in Title",
     "click_action": "FLUTTER_NOTIFICATION_CLICK",
 }
}

**important should add "android_channel_id": "default_notification_channel_id"**
